When none of the liquid drain cleaners worked, I decided to try this snake before calling a plumber. Very glad I did. Cleared the kitchen sink drain for much less than any plumber would charge. My clog was pretty far down the pipe, but this 25 ft snake was long enough to do the job. The whole job also took less than 30 minutes which was great. For the money, this is a great snake to try before calling a plumber. Thanks!!
